User data

[JoeJ]

3.14 had user pointers. Is there something similar in 4?
Did not find anything in the dgBody class at least, so probably not.

But maybe i missed something. It would like to put some bit packed information to the bodies.
To implement things like ray or collision filtering.

Oh, and another question. Is there something like packet traversal for ray tracing?
Currently i trace rays from foot body corners down to check for the ground.
But each foot has 2 bodies, so that's 16 rays just for that. But they all have the same direction and start from nearby locations.

It is the ndNotify class, check out any demo.

That object now encapsulates, code and data, so it is much more flexible than it was in 3.
